Overview
The CC2500RGPR from Texas Instruments is a low-cost, low-power 2.4 GHz RF transceiver designed for very low-power wireless applications. It operates within the 2400-2483.5 MHz ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency band. The transceiver is integrated with a highly configurable baseband modem, supporting various modulation formats such as OOK, 2-FSK, GFSK, and MSK, and has a configurable data rate up to 500 kBaud. The CC2500RGPR is suitable for systems requiring low power consumption and high performance in wireless communication.
